沈阳市地表水环境承载力及水污染特征分析

根据2021年沈阳市78个地表水断面(点位)水质的监测结果,计算出2021年沈阳市水质时间达标率为85.6%,水质空间达标率为89.7%,水环境承载力指数为87.7%,为临界超载状态。通过对沈阳市监测断面超标情况进行分析,指出沈阳市地表水污染特征和污染原因,并提出对策和建议。

By analyzing and evaluating the monitoring results of 78 surface water monitoring sections(sites)in Shenyang,the time standard rate of water quality in Shenyang is 85.6%,the space standard rate of water quality is 89.7%,and the water environment carrying capacity index is 87.7%,which is a critical overload state.This paper analyzes the situation of monitoring section exceeding the standard in Shenyang,points out the pollution characteristics and causes,and puts forward countermeasures and suggestions.
